United States Patent 2,957,2s9 Patented Oct. 25, 1960 MACHINE FOR FABRICATIN G CONTAINERS Charles Z. Monroe, Detroit, and Harry B. Eglestou, Livonia, Mich., assignors, by mesne assignments, to Ex-Cell-O Corporation, Detroit, Mich., a corporation of Michigan Filed July 16, 1957, Ser. No. 672,200

11 Claims. (Cl. 53-186) The present invention relates in general Ito carton forming machinery of the type disclosed in United States Patent Nos. 2,357,535 and 2,367,884, issued September 5, 1944, and January 23, 1945, respectively, on the application of Charles Z. Monroe. More specifically, the invention is concerned with an improved machine yfor forming, coating, filling, closing and sealing gable top containers of paperboard or the like. The machine fnds particular, but not exclusive, utility in producing, from fiat collapsed blanks, finished `and filled cartons of the type shown in United States Patent No. 2,750,095, issued June 12, V1956 on the `application of Carroll ,R. Alden.

`One object of the invention .is to provide a carton forming machine of theV character set forth .and which will be more compact than machines of the kind Vheretofore known so as to permit both loading and discharge to be handled by a single operator.

Another object is to provide a machine of the foregoing type having an improved sealing and stapling mechanism which will produce cartons with top closures which are more effectively sealed than in prior machines of this nature.

A further object is -to provide a machine of the character set forth and which, when installed in a dairy or food packaging plant, will lend itself readily to sanitary maintenance without interference with its component mechanisms.

The foregoing and other objects will become apparent as the following description proceeds, taken together with the accompanying drawings, wherein:

Figures l and 2 are perspective views showing opposite sides of an illustrative machine embodying the present invention.

Fig. 3 is an enlarged end elevation of the blank magazine situated on top of the machine and taken from the rear of the stack.

Figs. 4 and 5 are enlarged elevation and plan views, respectively, of the blank magazine and feeder unit of the illustrative machine.

Figs. 5A, 5B and 5C are fragmentary plan views showing portions of the mechanism illustrated in Fig. 5 and, in the case of Figs. 5B and 5C, in different operative positions.

Figs. 6, 6A and V7 are enlarged elevational views illustrating the loading mechanism for applying an openended tubular blank to a mandrel.

Figs. 8 and 9 are vertical sectional views showing the mandrel assembly of the machine together with related mechanisms and assemblies.

Fig. 9A is an enlarged sectional view of the stripper mechanism taken in lthe plane of the line 9A-9A in Fig. 9.

Fig. 10 is an enlarged, fragmentary end elevation of the machine with portions of the cooling compartment broken away to show internal mechanism.

Fig. 11 is an enlarged vertical sectional view'through Y the cooling compartment of the machine and taken in the plane of the line 11-11 in Fig. 12.

Fig. l2 is an enlarged horizontal sectional View through the cooling compartment, taken in the plane of the line lil-12 in Fig. l1.

Figs. 13 and 14 are elevation and plan views, respec-v tively, showing the intermittently operated conveyors of the machine and the mechanisms cooperating therewith.

Figs. 15 and 16 are side and end elevational views showing the filler unit of the machine.

Fig. 17 is an enlarged, fragmentary perspective view showing certain details of the iller unit.

Figs. 18, 19 and 2O are enlarged vertical sectional views through one of the filler heads of the filler unit, and Figs. 18A land 18B are fragmentary views detailing certain parts of the ller unit.

Fig. 21 is a side elevation of the sealing and stapling mechanism of the machine, together with its supporting column.

Figs. 22 and 23 are enlarged fragmentary elevational views showing the jaws of the sealing and stapling mechanism, certain parts in Fig. 22 being shown in vertical section.

Figs. 24 and 25 are enlarged fragmentary plan views of that portion yof lthe mechanism shown in Figs. 22 and 23.

Figs. 26, 27 and 27A are enlarged fragmentary plan views showing internal parts of the sealing and stapling mechanism in dierent operative positions.

Figs. 28 and 28A are enlarged fragmentary vertical sectional views detailing internal parts of the sealing and stapling mechanism in different operative positions.

Fig. 29 is a diagrammaticplan view showing the mechanical power connections between the principal mech-` anisms of the machine.

While the invention is susceptible of various modications and alternative constructions, a certain illustrative embodiment has been shown in the drawings and will be described below in considerable detail. It should be understood, however, that there is no intention to limit the invention to the specific form disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions yand equivalents falling within the spirit and scope of the invention as eX-v pressed in the lappended claims.

General machine organization Referring more specifically to Figs. l and 2, the invention is there shown exemplified in a novel machine 36' for fabricating containers of paperboard or the like. The ma# chine is adapted to receive a supply of at tubular blanks which are appropriately cut and scored, and to operate on them in such a manner that a procession of iilled and sealed containers is discharged therefrom. In the course of such operation, each at tubular blank is withdrawn from a stack or magazine by means of a feeding mechanism, is erected into a tubular form and passed throughH ya bottom forming mechanism, a moistureproof coating mechanism, anda cooling mechanism, the container then being lled, closed, sealed, and discharged from the machine.

The machine 30 is particularly well adapted to produce paper containers such as the `familiar gable top paper milk container disclosed in Alden U.S. Patent No. 2,750,- O95, supra. This container comprises a single sheet of paper or paperboard cut and scored so as to be divided into a plurality of panels and areas which are utilized for the walls of the container and the closure parts when the container is erected. The blank, as presented to the machine, is folded upon itself and has its side seam already glued, thus defining a collapsed, open-ended tube.
